Abstract： It is well known that the increasing dosage of high Mg-containing V-bearing titanomagnetite, the iron ore was adopted for the iron works at Panxi area of the Southwest China and correspondingly the MgO content (%mass fraction) increased gradually in the blast furnace slag. In view of the above fact, it is meaningful to investigate the influence of MgO content on the viscous flow property of high-Ti blast furnace slag containing high melting point material, such as TiC, TiN, Ti(C, N) etc. Results show that the blast furnace slag containing 20% TiO2 and 14% A12O3 presents the so call "short slag" characteristic with binary basicity R2 in a range of 1.0～1.2, of which the melting temperature increases from 1332℃ to 1364℃ with the increasing MgO content from 8% to 12% . At temperatures above 1450℃, the slag viscosity is lower than 0.3 Pa·s with a good liquidity, which can meet the requirements for the smooth operation of blast furnace.

Abstract：基于同时满足连铸水模拟实验中Re和Fr相似要求，建立了一套可全尺度模拟连铸过程流动的实验平台。利用该平台的NI图像处理与PIV粒子测速技术，对特厚板连铸用中间包内速度场、涡量场、RTD等流动特征进行研究。结果表明，中间包内流动呈现湍流漩涡状，在注流区形成一个类似“漏斗”状的涡结构，由于中间包内通道的存在，在浇注区形成两个大的环流，并对侧墙有明显冲击，非接触测量获取的RTD与数值模拟结果吻合，长的停留时间和大的死区体积表明该中间包补热的必要性。
